A whale species never before recorded in Irish waters has been confirmed by the Irish Whale and Dolphin Group (IWDG).

The marine wildlife specimen reported at Glengarriff in West Cork on 1 May — which live-stranded before it was found dead the following day — is that of a dwarf sperm whale, IWDG strandings officer Stephanie Levesque said.

Video footage received of the whale was shared with international experts “who confirmed that in their opinion it was a dwarf sperm whale due to its taller dorsal fin and smaller back”.

Levesque acknowledged concerns over the distress of the animal in the supplied video but said that “there is nothing [anyone] could have done as it was thrashing violently on slippery, seaweed covered rocks … It is extremely important to understand, if you see a stranded animal thrashing violently in this way, as difficult as it is to watch, you must keep your distance.”

The 2.25-metre female whale was with calf when it died, and a post-mortem by Drs Jim Donovan and Mercedes Gomez-Parada at the Cork Regional Vet Lab could not confirm the cause of death.

“Prey remains, including squid beaks, were found in its stomach which was recovered together with the whole intestine for further analysis,” Levesque added. “The skeleton will be prepared by the IWDG and donated to the National Museum of Ireland (Natural History) to be preserved by the State.”

Meanwhile, genetic testing of a skin sample was performed by Dr Eileen Dillane, a geneticist at UCC’s School of Biological, Earth and Environmental Sciences, who identified a 99% match with the genes of dwarf sperm whales from the Western North Atlantic.

The last known record of a dwarf sperm whale in this part of the world was a sighting off Cornwall in the UK in October 2011.

“Whether we might expect more strandings of this ‘warm water’ species in Ireland and the UK following the impacts of climate change remains to be seen, but it is very important to continue to report stranded cetaceans to the IWDG so we can monitor these trends into the future,” Levesque said.

This was the second animal to be examined under the new Deep-Diving and Rare Cetacean Investigation Programme (DDRIP) launched by the IWDG recently.

Ferry & Car Ferry News The ferry industry on the Irish Sea, is just like any other sector of the shipping industry, in that it is made up of a myriad of ship operators, owners, managers, charterers all contributing to providing a network of routes carried out by a variety of ships designed for different albeit similar purposes.

All this ferry activity involves conventional ferry tonnage, 'ro-pax', where the vessel's primary design is to carry more freight capacity rather than passengers. This is in some cases though, is in complete variance to the fast ferry craft where they carry many more passengers and charging a premium.

In reporting the ferry scene, we examine the constantly changing trends of this sector, as rival ferry operators are competing in an intensive environment, battling out for market share following the fallout of the economic crisis. All this has consequences some immediately felt, while at times, the effects can be drawn out over time, leading to the expense of others, through reduced competition or takeover or even face complete removal from the marketplace, as witnessed in recent years.

Arising from these challenging times, there are of course winners and losers, as exemplified in the trend to run high-speed ferry craft only during the peak-season summer months and on shorter distance routes. In addition, where fastcraft had once dominated the ferry scene, during the heady days from the mid-90's onwards, they have been replaced by recent newcomers in the form of the 'fast ferry' and with increased levels of luxury, yet seeming to form as a cost-effective alternative.

Irish Sea Ferry Routes

Irrespective of the type of vessel deployed on Irish Sea routes (between 2-9 hours), it is the ferry companies that keep the wheels of industry moving as freight vehicles literally (roll-on and roll-off) ships coupled with motoring tourists and the humble 'foot' passenger transported 363 days a year.

As such the exclusive freight-only operators provide important trading routes between Ireland and the UK, where the freight haulage customer is 'king' to generating year-round revenue to the ferry operator. However, custom built tonnage entering service in recent years has exceeded the level of capacity of the Irish Sea in certain quarters of the freight market.

A prime example of the necessity for trade in which we consumers often expect daily, though arguably question how it reached our shores, is the delivery of just in time perishable products to fill our supermarket shelves.

A visual manifestation of this is the arrival every morning and evening into our main ports, where a combination of ferries, ro-pax vessels and fast-craft all descend at the same time. In essence this a marine version to our road-based rush hour traffic going in and out along the commuter belts.

Across the Celtic Sea, the ferry scene coverage is also about those overnight direct ferry routes from Ireland connecting the north-western French ports in Brittany and Normandy.

Due to the seasonality of these routes to Europe, the ferry scene may be in the majority running between February to November, however by no means does this lessen operator competition.

Noting there have been plans over the years to run a direct Irish –Iberian ferry service, which would open up existing and develop new freight markets. Should a direct service open, it would bring new opportunities also for holidaymakers, where Spain is the most visited country in the EU visited by Irish holidaymakers ... heading for the sun!
